Re: freemarker binding issue .

I'm not sure that you're getting the split between server side processing and client side code.   Freemarker generates the text of the page.  Period.  That text may or may not be html/javascript.  Html/javascript does not know that freemarker exists and more or less vice-versa.   The same is true for jsp and most other view generating stacks.  The nature of your question isn't really related to freemarker at all, it's more of a general web programming issue.

Whatever you are trying to do can be done very cleanly, but you need to think about it in a different way.
You can put server side code in and around javascript blocks to generate different javascript based on server side state.

[#assign serverSideVariable = true]
<script type="text/javascript">
function dynamicJavascript()  {
[#if serverSideVariable]
alert('serverSideVariable was true');
[#else]
alert('serverSideVariable was false');
[/#if]
}
</script>

Will only send

<script type="text/javascript">
function dynamicJavascript()  {
alert('serverSideVariable was true');
}
</script>

To the client.  The stuff in the square brackets is gone by the time that function gets sent to the client and runs...  I don't think this is what you're asking however.. I think your addWccRow is an ajax update request that goes back over to the server-side...

Thanks Daniel . I agree with your statement .

Is there way to increment a freemarker variable within a javascript function ?



Example of my FTL :

0)  <#assign row=0 />



1)  <@spring.bind "wccJobRecords.detailContent[${row}].accentity" />

<input type="text" size = "30"  maxlength= "30"  id="Entity_0"  name="${spring.status.expression}" value="${spring.status.value?default("")}" />



   2) Call addWccRow javascript function.



   3) function addWccRow(.......){

<#assign row=row+1 />



But when access the row variable in step 1 , it return 0 only , but I am expecting it to incremented .I think this is problem with scope of variables .

I tried with global also it did not work.



I am very new to freemaker , please help me to resolve this issue .



Regards,

Sarat

The question doesn't make sense this way. FreeMarker runs on the server, generates the HTML page that has no FreeMarker markup in it anymore, sends it to the client computer, then the JavaScript runs on the client computer in the Web browser.
